Nestorian Christianity

Nestorian Christianity is a Middle Eastern branch of Christianity. There are five pentarchs and autocephalous patriarchs, and their religious center was Antioch. They were the official Christian church of the Sassanid Empire.

History
Nestorianism is an early Christian branch which states that Christ has two separate natures - one divine and one human. This is the opposite of the Monophysite position where Christ has but a single nature. The nominal head of the Nestorian Church is the Patriarch of the East.
